Hi to all, I successfully cross-compiled the Qt 5.9.2 with support for EGLFS, following the “official” guide: https://wiki.qt.io/RaspberryPi2EGLFS .
Now I am able to run the qopenglwidget example at 60FPS directly from terminal, without a x11 environment. I also cross-compiled Qt3D module without problems, getting the sources from “git://code.qt.io/qt/qt3d.git -b origin/5.9.2”. I need a Qt3D version greater that 5.7 because I need the support for QPaintedTexture. The problem is that I am not able to run Qt3D example or application. I tried with several examples such as simple-cpp, lights and materials, the screen shows strange artifacts and the application seems freezed. When I try planets-qml I get this output: “QOpenGLTexture* Qt3DRender::Render::GLTexture::buildGLTexture() could not find a matching OpenGL ES 2.0 unsized texture format QOpenGLTexture::setMipBaseLevel: requires OpenGL >= 1.2 or OpenGL ES >= 3.0 QOpenGLTexture::setMipMaxLevel: requires OpenGL >= 1.2 or OpenGL ES >= 3.0 FBO incomplete FBO incomplete …” I also tried a custom application that works fine on PC getting this output: “EGLFS: OpenGL windows cannot be mixed with others. Aborted” I found this bugreport “Qt3d examples not working on Raspberry Pi 3 “ : https://bugreports.qt.io/browse/QTBUG-59349 . The bug has been fixed on v5.9.2, but It doesn’t seems true or I probably miss something on Qt3D cross-compilation. Has anybody succefully compiled a working Qt3D module (version >= 5.8) for RPi3 ? Thanks, Carlo
